Its my understanding that they are usually between the ages of 17 to 23. There are some outliers outside this range but the last time I saw a competitive gamer that young was during Halo 2 and the e-sports game has changed a lot over that time.

I thrive under stress. Pressure induces a 'process optimisation' state in me were I whittle down all of the things I have to do to the most important. Although this takes a lot more effort and I would prefer to not have stress all the time.

I would do the same but I wouldn't get angry or upset because someone offended them. I would react how I think that my friend would want me to react. If they wanted me to just talk to them and comfort them I'd do that. If they wanted me to declare war on a sovereign nation then I'd do that. Iv'e invested time into this person that I like and It's my job to protect that investment. However like I said, I don't feel offended by it.
